Gelatine membrane filters in conjunction with the MD8 air samplers (gelatine filter method) are used for the collection of airborne microbes and viruses. These filters are completely water-soluble, therefore, microbes in one sample can be cultivated in different nutrient media or low and high bacteria counts can be measured.

• Pre-sterilized and ready to use
• Maintains viability of the collected microorganisms
• Solubility of the filter is a prerequisite for virus sampling
• Air flow rate: 2.7 L/min/cm² (0.05 bar)

'Absolute' retention rate of 99,9995% for Bacillus subtilis and niger spores and 99.94% for T3 phages.
